Frequently Asked Questions
Q
Is this silicone tubing safe for direct food contact?
Yes. Our food-grade silicone tubing complies with U.S. FDA 21 CFR 177.2600, EU EC 1935/2004, and China GB 4806.11 standards. It is free from BPA, phthalates, and other harmful substances, making it fully safe for direct food and beverage contact.
Q
What temperature range can this silicone tubing withstand?
The tubing operates stably from -60℃ to 220℃, with short-term tolerance up to 250℃. This makes it suitable for both freezing applications and high-temperature sterilization processes.
Q
Can the silicone tubing be sterilized using CIP or SIP methods?
Yes. The tubing fully supports CIP (Clean-in-Place) and SIP (Sterilize-in-Place) procedures. It can also be cleaned using hot water, steam, or food-safe detergents without compromising its material integrity.
Q
Are custom sizes and colors available?
Yes. The standard color is high transparency, but custom colors are available upon request. Inner diameter sizes range from small to large bore and can be fully customized according to customer drawings and specifications.
Q
Is this tubing suitable for pharmaceutical and laboratory use?
Absolutely. The tubing is widely used in pharmaceutical liquid transfer, laboratory reagent delivery, and bioreactor connections. Its platinum-cured silicone construction ensures purity, chemical stability, and compliance with stringent industry standards.
Q
How should I store the silicone tubing to maintain its quality?
Store the tubing in a cool, dry, and well-ventilated environment away from direct sunlight, heat sources, and sharp objects. Avoid prolonged exposure to strong acids, alkalis, or solvents, and conduct compatibility testing before use in such environments.
